How Crank Ranks & Privacy

Explainable destination judgment over borrowed recall. Zero ads, zero behavioral profiles.

1. RANKING PHILOSOPHY Deterministic Extractors

Judging Destinations by Structure, Evidence & Friction

Commercial search engines reward SEO preambles, affiliate roundup mills, and pages packed with display ad networks. Crank retrieves candidate URLs from upstream recall and re-ranks them using deterministic HTML and structured-data extractors:

Recipes (recipes.v0.1): Parses schema.org/Recipe and DOM structure to reward clear ingredient lists, metric gram weights, and first-hand testing notes while penalizing 1,000-word SEO preambles, ad scripts, and modal popups.

Product Research (products.v1): Elevates stated testing methodology, lab measurements, hardware teardowns, diagnostic/repair guides, and enthusiast community threads while penalizing single-brand e-commerce catalogs and high-affiliate roundup listicles.

PageYank Lab Friction: Joins real-browser friction measurements (domain_yank) to demote pages with severe layout shifts, autoplay video players, and tracker bloat.

2. EPISTEMIC HONESTY Measured vs. Not Assessed

Missing Evidence Is Never Treated as Evidence of Absence

Every result card includes a “Why this page” inspection drawer showing the exact linear formula and measured attributes that determined its position.

When a candidate page has not been fetched within the live latency budget (or blocks automated inspection), Crank never invents a fallback penalty or claims “0 ad networks.” Uninspected pages are explicitly marked Not assessed (unfetched) and ranked neutrally by query relevance and any known domain-level PageYank measurements.

3. PRIVACY & DATA FLOW No Referrer Leakage

What Crank Stores and What Leaves the Server

No Behavioral Tracking: Crank Search uses zero third-party analytics SDKs, zero tracking cookies, and zero ad networks.

Outgoing Link Protection: All Crank pages send Referrer-Policy: no-referrer and mark external links with rel="noopener noreferrer" so destination websites never see the search query you typed.

Crawler Protection: Dynamic search result routes (/search?q=...) send X-Robots-Tag: noindex, nofollow so queries are never indexed by third-party search crawlers.

Upstream Recall Provider: When a query is not already cached in Crank's database, the search phrase is forwarded server-side to the Brave Search API to retrieve candidate URLs without forwarding your IP address, cookies, or browser headers.
